Lexus IS III (XE30) (2013 – 2020)

Reliability score : 9.2/10

The third-generation Lexus IS (XE30) marks a stylistic and technical turning point for the Japanese premium compact sedan. Introduced in 2013 and facelifted in 2016 (then heavily revised in 2020 in certain markets), it definitively abandons diesel engines (which caused problems on the previous XE20 generation) to focus on gasoline and hybrid powertrains. In Europe, the IS 300h hybrid version accounted for the overwhelming majority of sales. In North American and Asian markets, naturally aspirated V6s (IS 250, IS 350) and the 4-cylinder turbo (IS 200t / IS 300) dominated. The XE30 is renowned for its exceptional build quality, dynamic chassis, and overall reliability that vastly outperforms its German competitors (ADAC breakdown rate of only 1.2/1000 vehicles/year).

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The third-generation Lexus IS (XE30) is one of the most reliable premium sedans on the used market. By turning its back on diesel, Lexus eliminated the main sources of breakdowns from the previous generation. The IS 300h is the most rational and safest choice in Europe, offering unmatched hybrid reliability and negligible maintenance costs. For fans of traditional combustion engines, the IS 350 (3.5L V6) is a monument of reliability and driving pleasure, although rare in Europe. The IS 200t offers a good modern compromise. The only real flaws of this car are its dated infotainment system, its limited rear space, and the asymmetrical wear of the front tires (easily correctable with reinforced bushings). A highly recommended purchase for anyone seeking peace of mind.
